"Mob Wives" star Renee Graziano was rushed to a NYC hospital by ambulance today ... just hours after feds busted her father and several other Bonanno crime family members.

Sources close to the Graziano family tell TMZ ... Renee had a panic attack, collapsed, and had trouble breathing when she got news that her dad, Anthony "TG" Graziano, had been arrested in an early morning raid.

A "Mob Wives" rep confirms Renee was admitted to the emergency room and is still getting treatment right now.

Further upsetting for Renee -- the fact her ex-husband played a role in her father's arrest. Hector Pagan, who's appeared on the VH-1 show, has reportedly turned rat for the DEA.
